If download contains video files, this script searches subtitles on various web-sites and downloads them into destination directory. You can specify the language or multiple languages.

This post-processing script is a wrapper for Subliminal, a python library, written by Antoine Bertin (Diaoul Ael). All credit goes to the original author.

The library and the script are written in Python and work on all platforms supporting Python including Linux, Mac, Windows.

Subliminal uses video hashes and the powerful guessit library that extracts informations from filenames or filepaths to ensure you have the best subtitles. It also relies on enzyme to detect embedded subtitles and avoid duplicates.

Unpack into pp-scripts directory. Your pp-scripts directory now should have folder "subliminal" with subfolders "lib" and "subliminal" and other files;

That's it.

NOTE: To download subtitles from site BierDopje package "python-lxml" must be installed. I haven't tried this yet and therefore can't give you more detailed advices but I'll try this later and write back.

UPDATE Aug 2014:
A newer version of this script is developed by i2g and discussed in this topic.

I am using NZBget v11 with Subliminal as ppscript to download english subtitles. I tried it several times, for instance with movies and TV shows (Modern Family 5x01 aired some weeks ago). Everytime it downloads the wrong subtitle. For example, for Modern Family it downloaded 4x01 subtitles from opensubtitles, even though I checked there is the correct version on that website.

I cannot test anymore because I am away from where my raspberry pi with nzbget is located. But in the meanwhile I got a reply from the developer of subliminal and he confirmed that very soon ad complete new version of subliminal will be out, therefore I decided to wait and then see if I still continue to have the issue. If the problem will continue I will post the debug.

I have the same problem as Garret. Subliminal is downloading the wrong subtitles. Today I downloaded How I met your mother S09E08 and it downloaded the wrong subtitles (It did it with more, but I only have the log for this one).
Here is the log:http://pastebin.com/igu6cBxg
